bootstrap (AdminLTE) 文件上传向导未在复选框中显示上传的文件名

Question

我正在尝试使用 AdminLTE-3.0.5 入门模板开发仪表板。我编程在侧边栏上传文件，但上传的文件名没有显示在提供的框中。如果我将鼠标悬停在框上，我可以在工具提示文本中看到上传的文件名。修改后的起始页如下所示。我错过了什么？谢谢

Answer 1

在正文底部提供的以下必需脚本似乎应该在头部部分。

  <!-- REQUIRED SCRIPTS -->

  <!-- jQuery -->
  <script src="./AdminLTE-3.0.5/plugins/jquery/jquery.min.js"></script>
  <!-- Bootstrap 4 -->
  <script src="./AdminLTE-3.0.5/plugins/bootstrap/js/bootstrap.bundle.min.js"></script>
  <!-- AdminLTE App -->
  <script src="./AdminLTE-3.0.5/dist/js/adminlte.min.js"></script>

Answer 2

你需要导入这个

<script src=".AdminLTE-3.0.5/plugins/bs-custom-file-input/bs-custom-file-input.min.js"></script>

和此代码初始化

<script>
$(function () {
  bsCustomFileInput.init();
});
</script>
